Abstract
Aeronautical Gas Distribution Device The invention relates to a method for supplying a hydrogen engine (200) comprising the following steps: - introducing a first volume of liquid hydrogen into an intermediate tank (120a, 120b); then - closing the intermediate tank; then - heating the intermediate tank until a distribution pressure and a distribution temperature are reached in the intermediate tank; then - supplying a hydrogen engine with the hydrogen contained in the intermediate tank until a cut-off temperature or a cut-off pressure is reached in the intermediate tank; then - closing the intermediate tank; then - purging the intermediate tank;The process is characterized in that the heating of the intermediate tank is maintained during the hydrogen engine supply stage with the hydrogen contained in the intermediate tank until the purge pressure is reached in the intermediate tank.
